When referencing the f distribution the numerator degrees of freedom are always given first as switching the order of degrees of freedom changes the distribution eg f 1012 does not equal f 1210for the four f tables below the rows represent denominator degrees of. To show the f1 score behavior i am going to generate real numbers between 0 and 1 and use them as an input of f1 score. This encouraged less risky driving.
It is calculated from the precision and recall of the test where the precision is the number of correctly identified positive results divided by the number of all positive results including those not identified correctly and the recall is the number of correctly identified positive.
